JavaScript - Javascript Experts: Help With Double Combo Box Please.
Hi, I'm Sam and I'm new to this forum. I have a few question about double combo box. Before I get down on details I have to confess that my knowledge about javascript is almost zer0 so if you're posting any answer please elaborate.
I've found this code somewhere online and I'd like to make some changes to this code. I've searched everywhere but couldn't find any answer yet. As you can see in this code, the javascript function can open a page in iframe once the user clicks on "Go". I'd like to know how to add links to the options in the first box so that it can open an iframe by itself, plus loads the next box , so when the user selects an option from the first box, the first box opens a page in iframe then loads the options for the second box. There should be two iframes side by side, the first iframe to open a page for the first box once the user selects the options in the box and the second ifram opens a page for second box once the user clicks on the "go". I just don't know how to add links to the options in the first box. Here's the code: Code: <html>

Similar Tutorialshi I wonder if someone out there can help me. I am very new to javascript and i have manged to understand a little of a double combo box with description however I would now like to be able to not only change the comment underneth but also add an image. This image (along with the comment) changes everytime the dropdownbox changes. I just cant seem to add the image. Please can anyone help I would really appreciate it and be extremely grateful. gr T I have the double combo script working on another website for an auto parts dealer with only 1 make so the options are Choose Model and then Choose Years for that model, i.e., 1979-1987 for one model and 1988-1994 for option 2 of the same model, and similar options for the other models. The links go to the cart for that Model/Year and everything works fine. This time I'm trying to set up the same script where this auto parts dealer has 21 Makes with a span of years for each make: 2011 to 1969, i.e., about 40 years for every Make. This parts dealer wants the years listed first and then the makes and from there I'll link to the cart for the model. I have the code set up (with only 4 years set up for the first Make as a test, which is VW/Audi) just so I can get it working, however after picking the year it's not letting me pick a make. It appears to choose one randomly with no other options. I have posted the code below minus most of the makes and years to save space I have three questions: 1. Is this the right script for this search pattern? 2. Is there a way to fix this so I don't have to list 40 years for every make?this would cause massive code bloat. 3. Is there an error in my code? PS. I'm not a Javascript programmer but do understand some of what it is doing. <form name="doublecombo"> <select name="example" size="1" onChange="redirect(this.options.selectedIndex)"> <option value="">Choose Year</option> <option>2011</option> <option>2010</option> <option>2009</option> <option>2008</option> <option>2007</option> <option>2006</option> <option>2005</option> <option>2004</option> </select><br> <select name="stage2" size="1"> <option value="">Choose Make</option> </select> <input type="button" name="test" value="Go!" onClick="go()"> <script> <!-- /* Double Combo Script Credit By JavaScript Kit (www.javascriptkit.com) Over 200+ free JavaScripts here! */ var groups=document.doublecombo.example.options.length var group=new Array(groups) for (i=0; i<groups; i++) group[i]=new Array() group[0][0]=new Option("VW/Audi 2011","http://www.....") group[0][1]=new Option("VW/Audi 2010","http://www.....") group[0][2]=new Option("VW/Audi 2009","http://www.....") group[0][3]=new Option("VW/Audi 2008","http://www.....") group[1][0]=new Option("Acura","http://www.....") group[2][0]=new Option("BMW","http://www.....") group[3][0]=new Option("Geo","http://www.....") group[4][0]=new Option("Honda","http://www.....") group[5][0]=new Option("Hyundai","http://www.....") var temp=document.doublecombo.stage2 function redirect(x){ for (m=temp.options.length-1;m>0;m--) temp.options[m]=null for (i=0;i<group[x].length;i++){ temp.options[i]=new Option(group[x][i].text,group[x][i].value) } temp.options[0].selected=true } function go(){ location=temp.options[temp.selectedIndex].value } //--> </script> </form> Hi guys, I need your help in this... I try to reuse double combo boz with description in http://www.javascriptkit.com/script/...ombotext.shtml... I need to make it load content from external div instead of text in array as description. This is because there are so many selection and some can refer to the same description. I already changed the description so it can read html tag. But I have no idea how to put div id inside array and load the div content. Anyone can help me solve this? Really appreciate your help Hello I'm using the combo box selection menu by Elviro Mirko from this site (http://www.javascriptkit.com/script/...plecombo.shtml) I have made amendments to show my own data, however what I would like to happen is if the user selects from the top combo only, then all the records would be shown, whereas selecting from the second combo merely 'drills down' and shows the records required. - Hope that makes sense. The code is as follows: Code: // first combo box
data_1 = new Option("Douglas - DIS", "$");
data_2 = new Option("Douglas - COE", "$$");
data_3 = new Option("Peel - DIS", "$$$");
data_4 = new Option("Peel - COE", "$$$$");
data_5 = new Option("Ramsey - DIS", "$$$$$");
data_6 = new Option("Ramsey - COE", "$$$$$$");
data_7 = new Option("Castletown - DIS", "$$$$$$$");
data_8 = new Option("Castletown - COE", "$$$$$$$$");
// second combo box
data_1_1 = new Option("Registry Office Douglas", "-");
data_1_2 = new Option("Broadway Baptist Church Douglas", "-");
data_1_3 = new Option("Finch Hill Congregational Church Douglas", "-");
data_2_1 = new Option("St Thomas's Church", "--");
data_2_2 = new Option("St Barnabas Church", "--");
data_2_3 = new Option("St George's Church", "--");
The HTML code is as follows: Code: <select name="combo0" id="combo_0" onChange="change(this);" style="width:200px;"> <option value="">Select a Register...</option> <option value="Douglas - DIS">Douglas - DIS</option> <option value="Douglas - COE">Douglas - COE</option> <option value="Peel - DIS">Peel - DIS</option> <option value="Peel - COE">Peel - COE</option> <option value="Ramsey - DIS">Ramsey - DIS</option> <option value="Ramsey - COE">Ramsey - COE</option> <option value="Castletown - DIS">Castletown - DIS</option> <option value="Castletown - COE">Castletown - COE</option> </select> <BR><BR> <select name="combo1" id="combo_1" onChange="change(this)" style="width:200px;"> <option value="">Select a venue...</option> </select> the link for the actual site is http://www.manxbmd.com/cgi-bin/db.cg...m;db=marriages If you choose Douglas-COE and search, then 0 records are found, if you choose Douglas-COE followed by St Thomas's then still 0 records are found but if you search the surname Allitson you'll see that there is a record there. I'm not sure where I've gone wrong - I'm completely new to Javascript.

After this code i want to populate values 3rd combo box by selecting values in the 2nd combo box ( which is cinema ) bt after applying all the posible option to solve this problm nd i m nt getting success ,so m writing to you people for ur help. i will explain u the whole matter thn u wil better understand my problm. i m making one website on multiplex( online ticket booking). so i saw the website of pvr cinemas nd i thought i wil impliment this ticket booking concept in my project, so for the fullfillness of this target i hav to take atleast 7 combo box , these combo box names are :- 1. Select City- (Like - New Delhi , Mumbai ,Kolkata ,Chennai) 2. Select Cinema(Hall Name) - ( Saket - New Delhi , South Ex. - New Delhi, Navi Mumbai - Mumbai , Salt Lake - Kolkata) 3. Select Movie- (Atleast 3 movies in each cinema nd somtimes it can more or less hall by hall ) 4.Select Date - (next 5 days of current date for advanced booking) 5. Select Time - (show time for each movie in each hall should be 3 shows, means if 3 movies are playing currently in 1 cinema thn we hav to mention show times with some difference for all 3 movies. ) 6.Select Price - ( price can b d same for all movies like - 150 (normal),250 (middle ) , 500 (high) ) 7. Select No. of Seats - ( no of seats for advanced booking is 1 to 10 for every film). your given link solved my 1st combo box problm dear bt nw facing another problm. i want to populate all the movies in 3rd combo box by selecting a cinema value in 2nd combo box . for example i selected " saket - new delhi " thn all the movies which r playing currently in this cinema should be comes in d 3rd com bo box . same as for other options south ex. - new delhi , navi mumbai - mumbai nd so on. i think this problm can be solved by three dimensional or multi dimensional arrays bt friends i dont hav much knowledge of multi dimensional arrays in javascript. if u people will help me to solve this problm thn i will be very thank full to all of you. i hav less time friends. so will u plz help me ??????? please reply me soon friends............ thank you Hi Everybody This is probably a very commonly asked question, however after much searching online I can't seem to find a straightforward answer. If anyone knows the code or a link to a place with a simple example it would be great. What I have got is a form that a user has to fill out and submit (when validated all variables are stored in a session and emailed after multiple forms are completed), currently I have radio buttons, text boxes and a combo box/ drop down list (for location). All parts are working fine and validating fine. My problem is to do with the combo box//ddl. I have successfully validated the ddl so the user must select a location onsubmit and it is added to session and passed fine. At the moment the ddl only has cities or towns in it however as I would like to include different states and possibly different countries I need a code that validates the state first and then only gives the cities/towns that are in that state (otherwise my ddl would be to large). I can do this with links however I can't seem to do it in a form. I am trying to do it this way DDL has list of all states that on mouseover/ onclick the list is revealed. onclick of a specific state populates another ddl with only the cities cities/ towns that are in that state and onclick of specific city selects the location whereby onsubmit the location is stored in the the session for submission by email Thanks in advance for your help I still have the following two major issues. 1) Firstly I need to be able to send the selection from the second combo box by php. 2) secondly I need the combo box to appear within the table. (I thought this should be easy, but for the life of me cannot figure out how to get the dynamic combo into my table inside the form) I have managed to send the selection from the first combo box with the form and also I can send a selection from the second combo, however onsubmit regardless of what is selected in the second combo box it simply sends the last option not the one selected. I have spent many hours trying to figure out why this is the case to no avail. I have included my code for anyone who may be able to help. Lastly when I have figured out these 2 (with a little help) I should be able to sort out the validation by myself. Please ignore any code that is not relevant <html> <head> <script type="text/javascript"> var this1; window.onload = function() { if (!document.all) document.captureEvents(Event.CHANGE); document.getElementById('myddl').onchange = readDDL1; } function readDDL1() { var ddlobj = document.getElementById('myddl'); var currentSelection = ddlobj.options[ddlobj.options.selectedIndex].value; if (currentSelection == '') currentSelection = ddlobj.options[ddlobj.options.selectedIndex].text; doDDL2(currentSelection); } function doDDL2(ddl1Selection) { var existingDDL2; if ((existingDDL2 = document.getElementById('myddl2')) != null) existingDDL2.parentNode.removeChild(existingDDL2); var ddl2Options; switch (ddl1Selection) { case "Western Australia": ddl2Options = ["Please Select A Location", "Karratha", "Perth"]; break; case "Queensland": ddl2Options = ["Please Select A Location", "Brisbane", "Gold Coast"]; break; } if (typeof ddl2Options == "object") { ddl2 = document.createElement('select'); ddl2.id = "myddl2"; var forVar; for (forVar in ddl2Options) { var newOption = document.createElement('option'); newOption.appendChild(document.createTextNode(ddl2Options[forVar])); ddl2.appendChild(newOption); } document.body.appendChild(ddl2); } document.testform.this1.value = ((ddl2Options[forVar])); } function checkFrequency() { return ShowResults(); } function validate(){ var digits="0123456789" var temp if (document.testform.location.selectedIndex == 0) { alert("Please Select a State"); return false } if (document.testform.location2.selectedIndex == 0) { alert("Please Select a Location"); return false } return true } </script> <style type="text/css"> .td_freq { background-color:yellow; height:40px; text-align:center; } .td_sev { background-colorink; height:40px; text-align:center; } .td_wi { background-color:lightgreen; height:40px; text-align:center; } </style> </head> <body> <FORM name="testform" action='./emlapd.php' method='post' onsubmit="return checkFrequency()"> <input type='hidden' name='this1'> <table align="center" border="1" width="40%"> <tr><td><b>Current Worksite State:</b><font color="red">*</font></td> <td> <select name="location" width='53' id="myddl"> <option value="0">--- Please Select Your State --- & nbs p; & n bsp; & nbs p; </option> <option value="Western Australia">Western Australia</option> <option value="Queensland">Queensland</option> </select> </td></tr> <tr><td><b>Location:</b><font color="red">*</font></td> <td> </td></tr> </table> <tr> <th colspan="2"> <input type="submit" name='submit' value="Submit" onclick= "return validate()"> </th> <td colspan="10"> </td> <th> <input type='reset' name='reset' value='Clear Form'> </th> </tr> </table> </FORM> </body> </html> Thankyou very much to everyone that may help So I can place the DDL inside the form, however it places it at the end of the form. I want it somewhere in the middle (immediately following first combo box) My other main issue is irregardless of the selection it simply posts the last option from the DDL not the one selected. Therefore I still want the second combo box to appear immediately below the first combo box and whatever option is selected from the second combo box I want to be posted with the rest of the form data. If you have any other ideas that would be great Obviously the reason I am still getting the same incorrect post is because the variable posted is still this1 from my code which reads the last value from the DDL. I have tried with all other variables to send as well ie ddl2 however still can't seem to send the selection. So in its current state how can I send the selection and place the second DDL within the form?? Thank you I have a page that is not displayable under Internet Explorer 8.0 (Chrome and Mozilla Firefox works fine), and the error is Message: 'clickcategoryID' is undefined Line: 50 Char: 2 Code: 0 URI: /includes/javascript/template_functions.js Below is the line from the template_functions.js where it is troubling, can anyone help me correctly identify it. S.O.S! function clickmenuhover() { if(!document.getElementById(clickcategoryID)) return false; ========================================================= function Rollover(imagename, image, over) { if(window.document.images) { if(over) { window.document.images["sdhover" + imagename].src = image; } else { window.document.images["sdhover" + imagename].src = image; } } } function ToggleCommentDiv(elm, hiddenDivName, ShowText, HideText) { var hiddenDiv = document.getElementById(hiddenDivName); if(hiddenDiv.style.display == 'none') { elm.innerHTML = HideText; hiddenDiv.style.display = 'block'; } else { elm.innerHTML = ShowText; hiddenDiv.style.display = 'none'; } } function ViewAllComment(url) { window.open(url, '', 'width=600, height=auto, resizable=yes,scrollbars=yes'); } function addLoadToEvent(func) { var oldonload = window.onload; if (typeof window.onload != 'function') { window.onload = func; } else { window.onload = function() { oldonload(); func(); }; } } function clickmenuhover() { if(!document.getElementById(clickcategoryID)) return false; document.getElementById(clickcategoryID).className = 'categoryclick'; } addLoadToEvent(clickmenuhover); ======================================================== I'm finishing up an e-commerce website, and I can't quite figure out why the shopping cart feature is acting all screwy in Internet Explorer. It works fine in Firefox, but in IE, when you add a product to the cart it doesn't display the little pop-up notification, and when you click on the "my cart" at the top right the product quantities are incorrect about 70% of the time. For some reason IE keeps doubling the quantities; I think one of the scripts may be double refreshing the page I just can't figure out where. If anyone has any suggestions they would be much appreciated. The site I'm referring to is he www.tcatvs.com Thanks y'all! Also I'm using the jquery framework for much of the site. Hello, I'm trying to achieve what seems pretty simple, I have achieved both aspects successfully by themselves but together I have not I am trying to submit a form data via post, then I'm also trying to redirect I have got the window.location working I have the database writing working however I can't seem to get them to work sequentially I think the reason is that the post action redirects to itself, then the initial setinterval request is gone I try to do the sequential action this way Code: <a href=# onclick="document.forms['frm'].submit();redirect();">Submit</a> So, either the data posts and I'm stuck at the same page, or it redirects and the data doesn't post What am I missing? I read that to have multiple functions by one click, you separate them with a semi-colon as I have done I think as I mentioned that the key is the post to PHP_SELF which "nullifies" the redirect request eg. it never existed So what do I do? Also I'm not after the time interval, I was just trying to find a way for a user to be notified "Hey you're going to be redirected" by an alert (which I had this pop up working as well) then when they press okay, they are redirected. Ideally the user enters data, data is stored, pop-up, hit okay, redirect Thanks for any help This is driving me nuts I need to replace all instances of "zz" with 'Z'. I can easily replace other strings such as a = a.replace(/mickeymouse/, "Z"); but a = a.replace(/zz/, "Z"); doesn't work. Must be a double characer thing? I am working on my personal portfolio site, and am using a code that will make each portfolio piece appear in a new div when the name of the piece is clicked on. The problem is, JS does not seem to recognize double digits. I am not familiar with JS at all, I just got comfortable with CSS/HTML a few weeks ago! I am in over my head. It would really, really help if someone could show me how to change the code so that I could make about 15 to 20 divs instead of 9. Here is the code: Code: <script language="JavaScript">
numdivs=9
IE5=NN4=NN6=false
if(document.all)IE5=true
else if(document.layers)NN4=true
else if(document.getElementById)NN6=true
function init() {
showDiv(0)
}
function showDiv( which ) {
for(i=0;i<numdivs;i++) {
if(NN4) eval("document.div"+i+".visibility='hidden'")
if(IE5) eval("document.all.div"+i+".style.visibility='hidden'")
if(NN6) eval("document.getElementById('div"+i+"').style.visibility='hidden'")
}
if(NN4) eval("document.div"+which+".visibility='visible'")
if(IE5) eval("document.all.div"+which+".style.visibility='visible'")
if(NN6) eval("document.getElementById('div"+which+"').style.visibility='visible'")
}
</script>
Thank you for taking the time to read this! Hopefully someone can help. Hello, I am very new to HTML and PHP but have managed to create a drop down "Surname" box on my website to list all the current surnames in my mySQL database. However, I also want the user to be able to type into the box and for the drop down list to automatically filter depending on the text the user inserts. I understand that this is not possible in HTML and PHP and requires some JavaScript, however I have never used this before and have no idea where to start. Any suggestions or help will be much appreciated. Here is my current HTML and PHP code... Code: $sql="SELECT Surname FROM Patients";
$result=mysql_query($sql);
?>
<form name="form" method="POST" action="<?php echo $_SERVER['PHP_SELF'];?>">
Surname: <?php echo "<select name=\"surname\">"; echo "<option size =30 ></option>";
while($row = mysql_fetch_array($result))
{
echo "<option value='".$row['Surname']."'>".$row['Surname']."</option>";
}
echo "</select>";
?>
Thank you! I have 2 combo boxes where you can move the items in combo box 1 to combo box 2. I want to validate that combo box 2 actually has something moved to it. How can I count the items in combo box 2. Combo box 2 will initially have no items in the box on page load. It is up to the user to move the items to combo box 2 and I want to make sure at least 1 item was moved.

Hi all, I have a form which takes some values as input and stores them in a db for another use. I have the following java script to validate the entries. Code: <HTML><HEAD><TITLE>Electronic Deposting Form</TITLE>
<script language="JavaScript">
<!-- script start
function validateComplete(formObj) {
if (emptyField(formObj.username))
alert("Please enter the Username.");
else if (emptyField(formObj.passwd))
alert("Please enter the Password.");
else if (emptyField(formObj.drop))
alert("Please enter the Drop Folder.");
else return true;
return false;
}
// Check to see if field is empty
function emptyField(textObj)
{
if (textObj.value.length == 0) return true;
for (var i=0; i<textObj.value.length; ++i) {
var ch = textObj.value.charAt(i);
if (ch != ' ' && ch != '\t') return false;
}
return true;
}
function chklen() {
var un = document.getElementById("username").value
var len = un.length;
if (len > 15) {
alert ("ERROR!!Only 15 characters are allowed in Username!!");
document.getElementById("username").value = un.substring(0,15); // remove excess characters
}
}
// script end -->
</script>
Now I am planning to add a combo box to the form where I have the environment field. Following is the code for the form. Code: <td align="left" valign="top"><FORM name="form" action="../saveDP.cgi" method="post" onSubmit="return validateComplete(document.form)"><TABLE width="100%" cellPadding=2 cellSpacing=2>
<TR>
<TD width="26%" class="label"><B>Username </B></TD>
<TD width="3%" class="label">:</TD>
<TD width="71%"><INPUT maxLength=255 size=28 name=username id='username' onkeyup="chklen()">
<TR>
<TD class="label" ><B>Password </B></TD>
<TD class="label">:</TD>
<TD><INPUT type=password maxLength=255 size=28 name=passwd>
<TR>
<TD class="label"><B> Environment </B></TD>
<TD class="label">:</TD>
<TD><SELECT class="input" size=1 name=environ>
<OPTION value=us selected><b> US </b></OPTION>
<OPTION value=uk><b> UK </b></OPTION>
</SELECT> </TD>
</TR>
<TD colspan="3"><table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="19%"> </td>
<td width="9%"><INPUT type=submit value=Submit v:shapes="_x0000_s1034"> </td>
<td width="8%"><input type=reset value=Clear v:shapes="_x0000_s1035\"></td>
<td width="64%"> </td>
</tr>
</table></TD>
</TR>
As I am new to JS, can anybody help me to implement a combo box( ie first two options are US and UK and third one is a text box which i can enter any value, can't be left blank while submitting the form) with "Environment" field? On a friend's site I am using a combination of easyslider (a slideshow script) and lytebox (probably doesn't need an intro). It can be seen in action on http://www.maisonportier.com/menu.php (then click on 'Press'). I really don't know much about Javascript so am just able to do extremely simple things such as combining two script. Now my friend want the slideshow to pause when an image is opened (using Lytebox), and to continue when the image is closed. The scripts can be found at: http://www.maisonportier.com/js/lytebox.js and http://www.maisonportier.comeasySlider1.5.js Can anybody tell me how to modify the code? Any help is greatly appreciated! Hello all, I have a form which contains some fields like company_name, address, phone, email etc. Also, I have a database with companies. I want that, when typing the beginning of the company name, a combo box to suggest all companies that match that text. I want that when a company is selected from the combo, all other textboxes to be filled with the correct info from the database. Also, I want that the user to be able to write a company that is not registered in the database. What I have done until now: For the editable combo I used the dhtmlxcombo from he http://dhtmlx.com/docs/products/dhtmlxCombo/ (Filtering mode: (filter existing list)). I'm not a scripting expert, so I think I cannot build this combo all by myself. I modified just one thing. At the begining, the dhtmlxcombo.js file contained something like this: Code: if (tab)z.tabIndex=tab;z.style.width = (width-19)+'px';self.DOMelem.appendChild(z);self.DOMelem_input = z;z = document.createElement('input');z.type = 'hidden';z.name = name;self.DOMelem.appendChild(z);self.DOMelem_hidden_input = z;z = document.createElement('input');z.type = 'hidden';z.name = (name||"").replace(/(\]?)$/, "_new_value$1");z.value="true";self.DOMelem.appendChild(z);self.DOMelem_hidden_input2 = z
I added z.id='dest_company';, so the file looks something like this, now: Code: if (tab)z.tabIndex=tab;z.style.width = (width-19)+'px';self.DOMelem.appendChild(z);z.id='dest_company';self.DOMelem_input = z;z = document.createElement('input');z.type = 'hidden';z.name = name;self.DOMelem.appendChild(z);self.DOMelem_hidden_input = z;z = document.createElement('input');z.type = 'hidden';z.name = (name||"").replace(/(\]?)$/, "_new_value$1");z.value="true";self.DOMelem.appendChild(z);self.DOMelem_hidden_input2 = z};dhtmlXCombo_defaultOption.prototype._DrawHeaderButton = function(self, name, width)
The text field 'dest_company' is generated like this: PHP Code: <select name="dest_company" id="dest_company" OnChange="SelectReceiver(document.comanda.dest_company.value);" style="width:206px;" tabindex="10"> <?php echo ' <option value=""></option>'; $address_result = mysql_query("SELECT * FROM `webdb_".$_COOKIE['user']."` ORDER BY companie ASC"); while($row = mysql_fetch_array($address_result)) { echo '<option value="'.$row['id'].'">'.$row["companie"].'</option>'; } echo ' </select> <script> var z = dhtmlXComboFromSelect("dest_company"); z.enableFilteringMode(true); </script>'; ?> This is the SelectReceiver() function: Code: function SelectReceiver(id_dest)
{
if (id_dest=="")
{
document.getElementById("contact_destinatar").value="";
document.getElementById("adresa_destinatar").value="";
document.getElementById("oras_destinatar").value="";
document.getElementById("judet_destinatar").value="";
document.getElementById("zip_destinatar").value="";
document.getElementById("telefon_destinatar").value="";
document.getElementById("mail_destinatar").value="";
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
//document.getElementById("detalii_destinatar").innerHTML=xmlhttp.responseText;
var response = eval(xmlhttp.responseText);
}
}
xmlhttp.open("GET","modifica_detalii_destinatar.php?q="+id_dest,true);
xmlhttp.send();
}
And the file modifica_detalii_destinatar.php looks like this: PHP Code: <?php $q=$_GET["q"]; include ('conectare.php'); $sql="SELECT * FROM `webdb_".$_COOKIE['user']."` WHERE id='".$q."'"; $result = mysql_query($sql); while($row = mysql_fetch_array($result)) { echo ' document.getElementById("contact_destinatar").value = "'.$row['contact'].'"; document.getElementById("adresa_destinatar").value = "'.$row['adresa'].'"; document.getElementById("oras_destinatar").value = "'.$row['oras'].'"; document.getElementById("judet_destinatar").value = "'.$row['judet'].'"; document.getElementById("zip_destinatar").value = "'.$row['zip'].'"; document.getElementById("telefon_destinatar").value = "'.$row['telefon'].'"; document.getElementById("mail_destinatar").value = "'.$row['mail'].'"; '; } ?> All this is working just in Firefox. In IE, when I select a company from the combo box, an error is generated and no text box is completed with the correct data. The error I'm talking about is: Code: 'document.comanda.compania_destinatar.value' is null or not an object In Firefox, if I inspect element with Firebug, my select looks like this: Code: <div style="width: 204px;" class="dhx_combo_box ">
<input type="text" autocomplete="off" class="dhx_combo_input" tabindex="10" style="width: 185px;" id="companie_dest">
<input type="hidden" name="dest_company" value="45">
<input type="hidden" name="dest_company" value="false">
<img class="dhx_combo_img" src="codebase_xcombo/imgs/combo_select.gif">
</div>
Any help on this would be great. Many thanks and best regards! |
